Message Description:

Flaps do not operate because of a latched fault. The flaps cannot be selected.

Possible Causes:

  • Slat Flap Control Unit (SFCU) (A95)
  • Slat Flap Control Unit (SFCU) (A124)
  • A mechanical jam in the drive line (after third try to move the system)
  • Loss of power to Flap System
  • Overheated flap components
  • There is a skew trip of the flaps
  • There is a flap mechanical disconnect
  • There is a flap overspeed condition
  • The flap is not rigged correctly
  • Associated Wiring

Troubleshooting Tips:

  • AW700-27-0373 - SFCU -17: "SLAT-FLAP HALFSPD" EICAS Nuisance Message

Forum Articles/Infoservice/Newsletter: None

Flight Operation Notifications Manual (FONM): 

[ Global Express ]  [ G5000 ]  [ Global XRS ] FON 01-11 FCLT−006 - [STALL WARN ADVANCE] (Caution /Amber]

NOTES:

  • If an SFCU seems to be in a locked up state, please refer to this Troubleshooting Tip for more information and instructions to resolve the issue.
  • To avoid the display of any Slat/Flap related CAS nuisance message after replacement of SFCU due to internal failure, follow AW 700-27-0373 instructions.
  • Execute two consecutive Slats and Flaps electrical rigging on CAIMS (All EICAS messages and CAIMS Active faults related to the Slat Flap Control System must be disregarded throughout the dual electrical CAIMS rigging process).
  • Once the two CAIMS SFCS rigging are completed, perform a complete aircraft power shut down.
